CellRenderers are used by Gtk::TreeView columns to render the Gtk::TreeModel column data appropriately.
They display, and allow editing of, the values of their properties. In most cases, Gtk::TreeView::append_column() will automatically choose the appropriate renderer for the mode column's data type, so you will rarely need to worry about these classes.

The three passed-in rectangles are areas in cr. Most renderers will draw within cell_area; the xalign, yalign, xpad, and ypad fields of the Gtk::CellRenderer should be honored with respect to cell_area. background_area includes the blank space around the cell, and also the area containing the tree expander; so the background_area rectangles for all cells tile to cover the entire window.

Glib::SignalProxy2< void,CellEditable*,const Glib::ustring& > Gtk::CellRenderer::signal_editing_started | ( | ) |
This signal gets emitted when a cell starts to be edited.
The indended use of this signal is to do special setup on editable, e.g. adding an EntryCompletion or setting up additional columns in a ComboBox.
Note that GTK+ doesn't guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of editable before doing any specific setup.
Note that this signal does not work yet in gtkmm. See http://bugzilla.gnome.org/show_bug.cgi?id=301597
